Acer AL2216W Repair Question

Re: Acer AL2216W Repair Question

When you work on the HOT side (PRIMARY), the cricuits ground for the hot side will be the neagtive leg of the main DC filter cap. If you do read 38vdc with the correct Ground point, then there is something wrong with that pin8 kick start pin of the TEA1532. You may want to trace out that connection to see if it is hooked at the same as shown in the app notes.

Checking it the way you said I now get 151 volts DC. Which to me sounds about right as I saw that the power goes though a resistor.

Ok I got the monitor working again. We had a bad trace from the resistor to the cap it was the leg that went to pin 1 of the SMPS ic. Now the only other problem I see but this more then likely a problem with the display as there are some pixels stuck on in two rows one straight up and down the middle and one horizontal about an inch up.

Thank you all for helping me.

Great, simply bad connections, no parts needed.
